TOOLSET / DISCOVERY + INDEXATION

See the page a crawler has to understand.

Technical SEO problems rarely live in one tag. Trace discovery, fetching, canonicalization, structured data, internal links, and performance signals as a connected path.

01 /

Check whether crawlers can reach the right URL.

Start with status codes, redirects, robots directives, and sitemap discovery before optimizing the content of a page that may not be indexable.

  • Trace redirect chains and verify the final canonical destination.
  • Inspect robots.txt groups, disallow rules, and sitemap declarations.
  • Validate XML sitemap files and indexes.
  • Find broken internal and external links that interrupt navigation.

02 /

Inspect the signals on the final page.

Review the metadata and structured information that help search engines interpret, consolidate, and present the page.

  • Check titles, descriptions, headings, canonicals, and robots metadata.
  • Extract JSON-LD, microdata, and other schema markup.
  • Preview Open Graph and social metadata.
  • Use Core Web Vitals and indexation checks as supporting evidence.

Choose the signal you need.

FAQ /

Operational detail.

Is one SEO score enough to diagnose a page?

No. Status, crawl rules, canonicalization, metadata, links, structured data, and performance are separate signals. Review the evidence behind each finding.

Can a sitemap make a blocked page indexable?

No. A sitemap helps discovery and communicates preferred URLs, but it does not override blocking directives, noindex, authentication, or inaccessible content.
